52 source surfaces: 47 bone meshes, two psoas major muscles, two external obliques and the diaphragm.
The sternum has three part meshes; mesh counts are not anatomical bone counts.
12 thoracic vertebrae, 5 lumbar vertebrae, sacrum, 24 ribs, manubrium, body of sternum, xiphoid process and two hip bones.
No cervical vertebrae, coccyx, intervertebral discs, costal cartilages, organs or other trunk muscles beyond these five surfaces.
OBJ vertices and triangulated faces preserved; no anatomical geometry invented, moved or mirrored.
Midline structures have no left/right side. Ribs use independently identified source surfaces.
Normals and illustrative colors are computed for display. Specialist anatomical review pending.
Per-mesh source names, FMA identities, OBJ checksums and output checksum: provenance.json.
